Lost account since 8/2025. Misti S. Refuses to return my calls

I had internet only at my address in Lithonia 12/2024. I purchased a cellphone from Xfinity 4/2025. Worst decision. I moved at the end of 8/2025. For an entire month they couldn't find any to install my internet in Fayetteville. When I went to turn in the equipment. I mentioned this to someone at the store. They scheduled someone that Sunday. Instead of him transferring my existing service he started a new account. I didn't know this at the time. I also didn't know at the time that my cellphone was linked to the same account. When I went to pay my cellphone in September they couldn't find my account. I didn't even have an account number. I was getting ready to go out of the state and they were going to turn off my phone. I had made countless calls only to get more frustrated with each call. My bill was supposed to be only $40 a month. They said that I hadn't paid my bill for four months. This wasn't true. I had the phone number of Ty in the resolution department. I left countless messages for him, because he is the one who sold me the phone he never returned any of my calls. I then started calling and pressing similar extension number trying to get anyone to help. I found some one who was willing to find someone to help. I received a call from Misti in Xfinity mobile executive resolution department. She told me that I didn't have to pay anything until 12/25. I got a bill 11/25 for double the amount I was supposed to pay only $40 a month. The bill was over $80. I have been trying to contact Misti since 11/2025 or anyone  in her department. I received a call asking me to pay $2. and some odd cents. They said that Misi couldn't credit the taxes. Now I'm receiving a message via text and email regarding an unpaid amount of $135.65. I called and I was told that I don't owe anything additional. The email says that my phone was turned off on 12/14/2025. Unfortunately it doesn't have an account number. I think this is the lost account. Misti started another account and the old account is just lingering. My account simply should have been transferred. All of this because I moved. I don't want this on my credit report. I thought that Ms. Misti handled this. She told me that she found my account that it has several zeros in front of it. Can someone call me to help me resolve this? The phone number to the xfinity account is [Edited: "Personal Information"]. I.can be reached on [Edited: "Personal Information"].
